To .(ILZZ mama Indy concern:

Beit known that 1, WILLIAM G. J oYoE, Jr. acitizen of the United Statesof America, and a resident of New York city, county and'State of NewYork, have invented certain new anduseful Improvements in'Bookbinding-Ma chines, of which the following is a specifica tion. w 7My invention consists ofvarious improvements in apparatus forautomatically feeding and placing the covers, feeding and placing theunbound books in the covers, pressing and sticking the covers. and"books together, and delivering the bound books out of the I5 machine,all as hereinafter described, reference being made to the accompanyingdrawings, in which- Figure 1 is a plan view of my improved ma chine.Fig. 2 is a detail, mainlyin plan View, but with some parts inhorizontalsection',

showing the rolls by which thepasted covers and the partly-bound booksare pressed after the books are placed in the covers; a vertical sectionpartly on line 2 2 of Fig. :1 and partly in the transverse central planeof the cover-supporting apparatus. Fig. 4 is a detail in verticalsection on line 4 4: of Fig. 1. Fig. 51s a side elevation as seenlooking from the right hand of Fig. 1,wi'th part of the frame cut awayon line 5 5, Fig. 3. Figs. '6 and 7 are two detail views of grippersforfeeding in the book-covers. Fig. 8 is a verticalsection of the upperpart ofthe-machine on line 6 6 of Fig. 1. Fig. 9 is a vertical sectionon line 7 7 of Fig. 1. Figs. 10 and '11 are side and frontviews,respectively, of details of the chain carriers, whereby the unboundbooks are transferred from the feeding-table on which the books areintroduced into the ma 4o chine and entered .into the covers. Fig. 12 isan end view of a book andcover on an en larged scale, showing therelations'of the parts when; the book leaves the pressingrolls. Fig; 13isa like'view showing the com- 5 pletely bound and pressed book with thecrease-joints of the cover and back as the book leaves the pressing andjoint-creasing apparatus. Fig. 14 is a detail of the pressing andjoint-creasing apparatus.

Arepresents a series of unbound books in the condition subsequent to therounding Fig. 3 is process, wherebythe backs are suitablyroundedras'shown at the bottom of said's'eries in Figf-9, preparatoryfor being inserted in the covers a. They are placed-upright on theirbacks side by sidetransversely'of anendless feedingapronc, carried .onrollsd over a tablee between side plates f. The-books are shiftedalong'intermitti-ngly the thickness of one book at each movement bymeans of a feeder comprising a yoke, whereof the two parallel bars g andthe cross-bar h, connecting them, form the parts. The cross-bar isplaced in slideways of the side platesfbehind the books, and the bars g,which'are toothed racks, reach forward and rest onthe retaining-pawls iand the feeding-pawls j. The pawlj of one side of the machineiscarried'on a lever 70, pivoted'on a shaft Z, and at its lower endcoupled to another lever'm, piv- 7o oted at n and connected by a stud 0with a groove in a rotating-cam 1'9, carried on a short shaft q. Thepawlj of the other side of the machine is carried on an arm 3 of thepivotshaft of lever 70.

Asrepresented in Fig. 9,-the series of books in t-he'feedway are atrestagainst a stop-gage t, preventing further advance of the books, Whileone, having passed the pasting-rolls M,

'has partly entered a cover a, which was previously'lying on the rolls2;, as indicated in .dotted lines, which rolls 0) grip and press thecoveronto the pasted sides of the book and discharge it preparatory toreceiving another book. I I

For delivering the nextbook to thepastingrolls the stop-gage t has firstto be shifted a quarterof a revolution on its axis 20,- said axisbeingsupportedonstandardsac. Theshifting is effected bya toothed spuryon the vertically- 0 arranged endless chain 2, engaging atoothed pinion2 on the axis 10 in its downward course, said chain and another likechain 3 being employed to grip the books successivelyas they aredelivered from the feedway and convey 5 them downward into the bite ofsaid'pastingrolls and thence into the covers. For so handling the bookssaid chains are arranged in the central vertical plane between saidpasting-rolls and also of the pressing-rolls o and at opposite sides ofthe feedway, respectively, in suitable proximity thereto forgrippingpads, as 4:, on the chain 2 and 5 on the chain 3 to grip theends of the books and control them while descending into thepasting-rolls. The length of the chains is in this example and the otherconditions such that each chain has two gripping-pads and is timed forsynchronism with the feeding, pasting, and pressing operations.

Immediately after the books pass the lower end of the stop-gage iintheir descent, said gage then occupying the position represented in Fig.5, another toothed spur 1 on chain z engages pinion 2 and shifts saidstop-gage into the position of Figs. 8 and 9 to prevent premature escapeof the books from the feedway.

The gage t is automatically operated and serves the double purpose of,first, gaging the forward movement of the books, and, second, gaging thedownward movement. j

The stop-gage t is made extensible lengthwise, as indicated, by the slot7 and clamping-screws 8 for accurate adjustment in that direction.

In the transverse direction of the stop-gage accuracy is not soessential.

On the side of the machine from which the covers a are introduced theend of the lower range of the chain 3 must be higher to avoidinterference with their introduction than will permit of the use ofbook-gripping pads directly connected to the chain, as they areconnected on the chain 2 of the other side. Consequently the pads 5 ofchain-3 are connected thereto by arms 9, reaching lower than the saidlower range of the chain, and said arms each have a spring 10 to effectthe gripping pressure. At 11 is a cam-cleat fixed in a suitable positionto retire the pads 5 through the instrumentality of a roller-stud 12,carried on the extremity of an arm 9 of each pad and running on saidcam-cleat' to enable the pads to pass the upper corners of the books, asshown in Fig. 10, without conflict. When said studs escape from thelower end of said cam-cleat, the pads 5 grip the book close to the loweredge, as shown in Fig. 8. The pads 45 of chain 2, being positivelyconnected to the chain, do not require such retiring movement to passthe upper covers of the books.

The chains ,2 and 3 are carried on upper sprocket-wheels 13 and 14 andlower sprocketwheels 15 and 16. Wheel 15 is carried on the short shaft(1, which also carries the grooved cam p, that operates the lever 'm, towhichlever 70 is coupled for operating the bookfeeding yoke. This shaftq is geared by a pair of bevel-wheels 17 with a shaft 18, which isgeared by a pair of bevel-wheels19 with the main shaft 20.

The lower sprocket-wheel 16 of chain 3 is carried on a shaft 21, that isgeared with the main shaft 20 by the spur-wheels 22, 23, and 24. Thepivot of the intermediate Wheel 23 of this train is carried in links 26,coupling it with the axes of" wheels 22 and 24, the

latter being carried on. shaft' 20 to allow the chain 3 to be shiftedtoward and from chain 2 for adjusting them to handle books of differentlengths. For so adjusting the chain 3 its shaft 21 is mounted onbrackets 27 and 28, that are adj ustably bolted on the framebar 29 at 30and to which the side plate f of the feedway on that side of the machineis attached, so as to be shifted accordingly. The upper sprocket-wheelof this chain 3 is mounted on a pivot-stud 31, carried on a standard 32,also attached to the side plate f for adjustment together with the rest.The cam-cleat 11 for retiring the gripping-pad 5 is also mounted on thisstandard 32. The upper sprocket-wheel 13 of chain 2 is also mounted on alike standard 33, attached to the other side plate f of the feedway.

Prior to the escape of the books through the pasting-rolls it the coversa have to be brought in and properly lodged over the pressing-rolls ofor reception of the books, as shown in Fig. 9. For this purpose theyare stacked in quantities from time to time on a platform 34 in duerelation to registering-gages 35 and 36, by which they are duly placedfor proper entry into the machine. The covers are taken one by one fromthe top of the stack over the upper ends of the gages 35, the platformbeing made to rise to the extent of the thickness of a cover as each oneis taken away, so that the gages 35 prevent more than one being taken ata time. For causing the rising movement of the stack of covers theplatform 34 is mounted on the upper end of a vertical screw-threadedstandard 37, which has support in the rotating screw-threaded nut 38,mounted in a supporting part 39 of the frame and being provided with'abevel toothed rim 39 with which a bevel-wheel 40 on the shaft 41 gears.The shaft 41 has a ratchet-wheel 42, by which a pawl on the lever m (seeFigs. 3 and 5) shifts said shaft 41 and the nut 38 intermittingly inunison with the feeding of the covers a. The shaft 41 consists of twoparts coupled by a clutch 4:3, with which an automatic uncoupling deviceis connected to take effect for temporarily interrupting the rise of thefollower incase its rate of movement is greater than the rate of thefeeding of the covers. The clutch is also used for disconnecting by handto run the platform down quickly by the hand-wheel 44, and thuseconomize time when a fresh stack of covers is to be supplied. Theautomatic device may be contrived in various different ways, and I donot limit myself to any particular construction. That which I haverepresented consists of the bell-crank 45, pivoted at 46, with one armconnected with-the shifting-hub 47 of the clutch and the other armconnected with one end of the rod 43, which is connected at its otherend with a short lever 49, which is pivoted at 50 and carries a stud-pin51 in its free end, reaching over the top of the stack of covers at oneside, as shown in Figs. 1 and 3, so that in case the IIO gage 36 is alsoadjustable, as at 59, for covers of difierent widths.

For feeding the covers into the machine two endless chains 53 are used,said chains being operated by sprocket-wheels 54 on the main shaft 20and running over carrying-wheels 55, turning on stud-pivots 56. Thesechains have gripping-jaws 57 to receive the covers, as shown in Fig. 5,and pull them along. The grippers are opened as they rise on thedriving-wheels 54 by contact of the rollers 60 of the gripper-jaws withthe stationary arms 61, under which said rollers pass, and the coversare thrust into the open jaws by pullers 62, hooking behind the rearedges of the covers and thrust forward by the rock-shaft 63, to whichthey are connected by arms 64; said rock-shaft being operated by an arm65, against the free end of which a tappet 65 on the tail end of theplates 67--by which the fixed jaws of the grippers 57 of one of thechains 53 are attached to it-makes contact at the moment the jaws areopened, the rollers 60 then escape from arms 61 and the jaws close onthe covers and carry them along on the ways 68 until, having reached theright point, the rollers 60 of the jaws pass under opening-studs 69 andrelease the covers. The chains 53 also have lateral arms 53, supportingthe covers at the outer edges. The grippers 57 are adjustable laterallyon the chains to adapt them for covers a of different widths, asindicated by the slot 70 in Figs. 6 and 7, and by the fastening-bolt 71in Fig. 6.

As the books vary a little in length and it is desirable to center thebooks in the covers lengthwise, I have contrived a centering deviceconsisting of a movable gage 72, resting on the ways 68, along which thecovers are brought in, against which gage the covers come to rest whenreleased from the grippingjaws. This gage 72 is jointed at 73 to a lever74, which is at 75 jointed to a fulcrumpivot. Said gage also has aspring 76 constantly bearing it to the right hand, Fig. 3, thus causingthe covers to be fed a little farther than the center. A rod 77 ispivoted to said lever at 78, which traverses the space down which thebooks feed a little to one side of the feedway and is connected to alink 79, pivoted to a supporting-bracket at 80, said rod having anextension-joint 81. At the joint of the rod 77 with the link 79 is aroller corresponding to that shown at 82, (see Fig. 9,) projectingthrough the slot 83 into the path of the descending books, so that thebooks will at one end touch and push the roller back to escape it, whichpulls the gage 72 through .into the bases of the bulging angles. pasteis applied to said pasting-rolls from the rod 77, and thus pulls thecovers back a little and centers them relatively to the books.

The aforesaid slot 83 is in one of a pair of thin plates 84, betweenwhich the books are guided onto the covers between pressing-rolls c,said guide-plates receiving the books from the pasting-rolls u, andcontrolling them until well in the control of the pressing-rolls o. Theplates 84 also serve to draw the pasted outer sheets of the books andsmooth out any wrinkles that may be in them. To these platesbuffer-springs S4 are attached to check the covers, which wouldotherwise be thrust against said plates by the pressing-rolls with toomuch impact.

The pasting-rolls are represented in Fig. 9 as having just dischargedthe book below and being ready for receiving another. The grooves 85 insaid rollers are intended to make free space for the bulging angles 86(see Figs. 5 and 12) resulting from the rounding of the backs, which itis desirable to retain as usual in bookbinding for prominent ridges overwhich to crease the back into the spaces 86 between said angles and theedges of the covers to form the joints of the covers with the backs.

In Fig. 5 it is to be observed that the pasting-rolls close on the sidesof the books immediately above the bulging angles 86 and at the momentsaid angles have entered the grooves of the pasting-rolls under theangles of the upper sides of the grooves, considering the positions ofthe rolls in said figure, so that the sides of the books are pastedclose The paste-boxes 86 by paste-feeding rolls 87, re-

.ceiving the paste through slots in the sides of said boxes andtransferring it onto the pasting-rolls against which they bear.

For driving the pasting-rolls a small pinion 88 on the shaft of thepressing-roll 1) gears with the spur-wheel 90, which gears with thepinion 91 on they shaft of the pasting-roll u at the right hand in Fig.5, and the other pasting-roll is geared to said spur-wheel by its pinion92 and an intermediate wheel 93, these being coupled by links 94 and 95,allowing the last-mentioned pasting-roll to be shifted toward and fromthe other to adjust them for books of different thickness.

The pressing-roll o is geared by apinion 96. on it with a pinion 97 onshaft 18, with which an intermediate wheel 98 also gears, and said wheel98 gearswith a pinion 99 on pressing-roll c, said wheels 99 98 and thepinion on shaft 18 being coupled by adjusting-links 100, allowingroll 1) also to be adjusted for books of different thickness.

The adjustable pasting-roll u, paste-box 86, standards x, carrying thestop-gage t, and the paper-smoothin g plate 84 of, the left-handside ofthe descending feedway (see Fig. 9) are all connected by brackets 87 foradjustmenttogether for books of difierent thickness. They are secured inposition on the rolls, they fall into pressing-racks on a rotating shaft41, by which they are pressed and creased and carried intermittinglyinto proximity to an endless carrier 101 and discharged thereon fordelivery to the place' for receiving them. The racks consist ofradiating plates 102, parallel to the shaft 41 and attached thereto,saidplates being flanged at the ends, as 103, and other plates 104:, alsoparallel to the shaft and flanged at the ends, as 105, the latter platesbeing connected at both ends to the former by the lazy-tongs links 106,whereof the outermost link at each end of the plates has a roller-stud107, with which stationary cams 108 take effect at the moment the booksare received between the two plates to grip the books for pressing andcreasing them and at the same time to carry them to the place fordischarging them, when by the escape of said studs from the cam the gripis relaxed and the books slide out onto the carrier 101, said cams andthe carrier for receiving them being arranged for the release when theracks are suitably inclined for the books to slide out. The fixed plates102 have a stop-rest 109, on which the books lodge when enteredproperlyin the racks, and both of the rack-plates have a creasing-rib 110 toproduce the j oint-creases 111 in the covers.

The combination of the bookfeedingway adapted to receive the. uncovered and back-rounded books in seriesand set upright on their backs, means for intermittingly feeding themalong sidewise, vertical endless chains and gripping-pads thereonadapted to receive the books endwise successively at the end of thefeedway, and pasting -rolls receiving the books from the chains andpasting the sides of the books preparatory to receiving the covers.
